@rizele Doing it for a friend. They wanted the same Android version as myself but we found some apps refused to work with microG. I was flashing the stock ROM according to Fairphone's instructions as the critical partitions needed to be flashed. Upon locking the bootloader I was unable to boot the phone. I knew what was wrong and what was needed to fix it, but the tool wasn't publicly available. That's where I raised it with them and argued over the pricing when their French repair partner was involved.

All in all, not an experience I would want again. This is my first, and will be my last, Fairphone device.
